python - セージで関数を呼び出す際のエラー

Question

SAES_ToStateMatrix([0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15])それが私に与えるように最初の関数を呼び出すときの人

[a^3 + a a^3 + a]
[a^3 + a a^3 + a]

SAES_FromStateMatrix([[a^3 + a a^3 + a],[a^3 + a a^3 + a]]) しかし、出力をエラーとして渡すことでエラーが発生し" invalid syntax "たため、このエラーを回避する方法

ここに私のコードがあります

F = GF(2);
L.<a> = GF(2^4);
V = L.vector_space();
VF8 = VectorSpace(F, 8);

def SAES_ToStateMatrix(block):
    r"""
    Converts a bit list into an SAES State Matrix
    """
    B = block;

    # form the plaintext block into a matrix of GF(2^n) elements
    S00 = L(V([B[0], B[1], B[2], B[3]]));
    S01 = L(V([B[4], B[5], B[6], B[7]]));
    S10 = L(V([B[8], B[9], B[10], B[11]]));
    S11 = L(V([B[12], B[13], B[14], B[15]]));

    state_matrix = Matrix(L, [[S00,S01],[S10,S11]]);

    return state_matrix;

def SAES_FromStateMatrix(state_matrix):
    r"""

    output = [];

            for j in xrange(4):
                output.append(Integer(v[j]));

    return output;
